[XML-SIG] Introducing me and my projects
Thu, 13 Feb 2003 15:13:48 -0200
Hello from Brazil!
I am a Python developer since a recommendation from Bruce Perens in 96 and
work (professionally) with Zope since 99. In 2000 I wrote the original
prototype which led to TAL and PageTemplates.
I recently wrote a reimplementation of TAL/PageTemplates based on a generic
XMLish transform engine, and this is where my interest in XML-sig
originates; I wrote a very generic XML (and XMLish [*]) library I call PAX.
[*] by XMLish I mean things that are "not quite" XML, like "classic" HTML
and documents that are primarily text with some XML markup in it
Altough the name PAX is a joke with SAX, it's really a DOM-like API similar
in spirit to elementtree (if I knew elementtree when I started I probably
wouldn't have, but now it evolved in its own right).
PAX includes the central element of OpenTAL, the transform engine
(pax.paxtransform). It badly needs some optimizing ;-) but it's very
I believe the library is now feature-complete, so I started the 1.0 cycle
(pending the optimization, but that will have to wait for my work schedule,
since the company allocated some time for that task later this month). I
would like to hear opinions on the library.
Since the beginning I released PAX into public domain because I always
intended to offer it for inclusion in the PyXML toolkit. Even if this
doesn't turn out to happen, I'm glad I did, because that forced me to write
a better, more generic API, IMHO ;-) and cleaner code.
The code is at http://savannah.gnu.org/opental/ - to see pax you just need
the pax release, on the other hand if you want opental you need pax.
(A quick paragraph about OpenTAL: the core feature is that it's easy to add
your own processing to the chain. I wrote it initially to support the i18n:
namespace, and that is implemented in a completely separate module just to
demonstrate this feature. Besides that, it also has a TALES context which
can be used sans Zope, and I'm in fact using it in a set of scripts for
generating static HTML from dynamic markup I call OpenTAL.Static - you can
check its progress by downloading OpenTAL, entering its directory and
running "cvs up -d".)
Those who trade freedom for security
lose both and deserve neither.
